“…The finding that Al induced a decrease in root and shoot Mg contents of the rice cultivars tested in this work agrees with other observations on rice (Fageria & Carvalho, 1982;Sarkunan & Biddappa, 1982;Jan, 1991) and wheat (Scott et al, 1992;Moustakas et al, 1995). This decrease in Mg irrespective of rice cultivars correspond to a decrease in Mg absorption and indicates a general Al effect rather than differential Al resistance, as has already been suggested for rice (Jan, 1991). Al-induced Mg deficiency has been associated with inhibition of Mg uptake (Huang et al, 1992) by blocking binding sites of transport proteins (Rengel & Robinson, 1989).…”

“…The question as to whether a more efficient transport of Ca in plants is associated with Al resistance is still unsolved. In this study, Ca translocation decreased in response to Al stress in Al sensitive cultivars Aiwu and IKP, a result that is in agreement with the findings of Sivaguru & Paliwal (1993), but not with the observations of Jan (1991). These discrepancies are unexplained but could be due to differences in cultivate behaviour.…”

“…In spite of a decrease in shoot K content of Al sensitive cultivars, no correlations among K content and differential Al resistance among the rice cultivars could be established, since, irrespective of Al doses, except for 1500 µM, Aiwu (Al sensitive) and the Al resistant (IRAT and IR) cultivars behaved similarly in the presence of aluminium. In rice, Jan (1991) observed that Al did not have a significant effect on shoot K content but increased root K content in all cultivars. However, this effect is not linked to differences in Al sensitivity.…”

“…However, studies devoted to the influence of Al upon mineral nutrition in plants frequently gave contradictory results. In rice, for example, there is no consensus that aluminium resistance is associated with more efficient transport of Ca: Sivaguru & Paliwal (1993) observed that Al resistant cultivars accumulated more Ca in their shoots than Al sensitive ones, but Jan (1991) reported that the Al sensitive cultivar IR45 retained more Ca in shoots than the Al resistant cultivate BG35 and concluded that Ca transport from root to shoot is not affected by Al in the sensitive rice cultivate IR45. In wheat, it is not clear whether differences in Al sensitivity among cultivars are due to differences in Al accumulation in the root system.…”

“…The increase in root P content associated with a decrease in shoot P content in Al sensitive cultivars Aiwu and IKP might be due to the formation of Al and P complexes inside the plant root, thus rendering part of the P unavailable for translocation within the plant (Sivaguru & Paliwal, 1993). In rice (Fageria, 1985;Jan, 1991;Sivaguru & Paliwal, 1993), wheat (Miranda & Rowell, 1989) and in certain pasture species (Andrew & Vandenberg, 1973), differential Al resistance has been correlated with differential abilities to absorb, to translocate and to utilise P in the presence of Al. Exposure to Al did not affect P concentration in root of Al-resistant Brachiaria cultivar, but it caused a 70% decline in P content of Al-sensitive Brachiaria cv (Wenzel et al, 2002).…”

The effects of aluminum (Al) stress on ion concentration and distribution were investigated in four rice cultivars (Aiwu and IKP, Al sensitive; IRAT112 and IR6023, Al resistant). Macro and micronutrient levels in plant tissues were markedly affected by Al and the magnitude of this effect depended on the cultivar group (Al resistance versus Al sensitivity) and on the concentration of Al in the nutrient solution. Al decreased Ca, P, K, Mg and Mn concentrations in shoot and K, Mg and Mn in root. It increased Ca and P in root and caused an increase in shoot and root Al contents. All these effects were observed in both cultivar groups, but were more apparent in Al sensitive ones. In conclusion, the results support the idea that, compared to the Al sensitive cultivars Aiwu and IKP, Al resistance in IRAT112 and IR6023 could be explained by a limited absorption and translocation of Al from root to shoot and could also be explained by a more efficient transport of Ca, P and Mn from root to shoot. These findings showed clearly that more than one mechanism may contribute to Al resistance in rice plants.

A presença do Al diminuiu a concentração de Ca, P, K, Mg e Mn nas folhas, mas a aumentou em K, Mg e Mn nas raízes. O Al causou aumento da concentração de Ca e P nas raízes e aumentou a sua quantidade nas folhas e raízes; esses efeitos foram observados nos dois grupos das cultivares, embora de forma mais marcada nas cultivares sensíveis ao Al. Os resultados reforçam a idéia de que, comparativamente às cultivares sensíveis Aiwu e IKP, a resistência ao Al nas cultivares resistentes IRAT112 e IR6023, pode ser explicada por uma absorção limitada e translocação do Al das raízes para as folhas e, possivelmente, por um transporte mais eficiente de Ca, P e Mn das raízes para as folhas. Os resultados mostram que mais de um mecanismo pode contribuir para a resistência ao Al, em plantas de arroz.Palavras-chave: mecanismo de resistência, alocação de nutrientes, oryza sativa

Responses of mineral nutrient contents and transport in red clover under aluminum stress

et al. 2021

Aluminum toxicity is considered the main factor underlying nutrient deficiencies and growth limitations of plants in acidic soil. Red clover (Trifolium pratense L.) is an important legume grass distributed worldwide, and it has medicinal value and strong adaptability to acidic soil with Al. However, few studies have focused on the relationship between nutrient uptake and Al stress. In this study, the changes in nutrients in the organs (root, stem, and leaf) of the cultivars Brilliant, Dory, and Haifa under high aluminum stress were detected. The results indicated that the contents of macronutrients and micronutrients were significantly influenced by Al3+ concentrations and the interaction between Al3+ concentrations and cultivars (P < 0.05). Under the Al3+ treatments, the contents of phosphorus (P) and magnesium (Mg) significantly decreased by 30.5% to 87.2% and 6.3% to 39.2%, respectively. However, potassium (K), zinc (Zn), and manganese (Mn) increased significantly, and these changes were closely correlated with Al resistance. The effect of Al stress on the copper (Cu) content varied with the plant organs, with Cu reduced in the roots but increased in the stems and leaves. Furthermore, the change ranges of nutrition contents in the sensitive cultivar were largest except for Cu. For example, the contents of Ca dropped by 26% in Brilliant leaves but decreased by less than 4% in the leaves of Haifa and Dory at 5‐mM Al3+. Moreover, the nutrient transport efficiencies were positively correlated with the Al3+ treatment concentrations in resistant cultivar except for Mg.

The root apex is considered the first sites of aluminum (Al) toxicity and the reduction in root biomass leads to poor uptake of water and nutrients. Aluminum is considered the most limiting factor for plant productivity in acidic soils. Aluminum is a light metal that makes up 7 % of the earth's scab dissolving ionic forms. The inhibition of root growth is recognized as the primary effect of Al toxicity. Seeds of wheat cv. Keumkang were germinated on petridish for 5 days and then transferred hydroponic apparatus which was treated without or with 100 and 150 μM AlCl3 for 5 days. The length of roots, shoots and fresh weight of wheat seedlings were decreased under aluminum stress. The concentration of K(+), Mg(2+) and Ca(2+) were decreased, whereas Al(3+) and P2O5 (-) concentration was increased under aluminum stress. Using confocal microscopy, the fluorescence intensity of aluminum increased with morin staining. A proteome analysis was performed to identify proteins, which are responsible to aluminum stress in wheat roots. Proteins were extracted from roots and separated by 2-DE. A total of 47 protein spots were changed under Al stress. Nineteen proteins were significantly increased such as sadenosylmethionine, oxalate oxidase, malate dehydrogenase, cysteine synthase, ascorbate peroxidase and/or, 28 protein spots were significantly decreased such as heat shock protein 70, O-methytransferase 4, enolase, and amylogenin. Our results highlight the importance and identification of stress and defense responsive proteins with morphological and physiological state under Al stress.
